  1. 1. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    University essay from KTH/Betongbyggnad

    Author : Mohammad Mustafa Angar; [2020]
    Keywords : Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Abstract : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. READ MORE

  3. 2. Probabilistic Assessment of Pile Drivability in Swedish Soils

    University essay from KTH/Jord- och bergmekanik

    Author : MAEDEH ALINEJAD KORDMAHALLEH; [2020]
    Keywords : Pile refusal; Monte Carlo method; probabilistic model; boulder.;

    Abstract : Site investigations are often performed prior to the design of pile foundations with the aim to collect data regarding soil properties including boulder content. The obtained data is typically limited due to non-homogeneous characteristic of the soil. READ MORE

  4. 3. WIND TURBINE FOUNDATIONS IN CLAY : Technical and economic considerations for proposals for wind turbine foundations

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Michail Papagiannis; [2018]
    Keywords : clay; wind turbine; bored pile; monopilem; soil stratigraphy; seismic loads; DIN; Eurocode;

    Abstract : This thesis approaches the problem of the cost-efficient wind turbine foundation on an onshore site of clayey soil characteristics. The given soil stratigraphy includes a layer of clay and two sands of different density. The characteristics of the soil and the water level that were used as input come from a site in Peloponissos, Greece. READ MORE

  5. 4. Automatingand optimizing pile group design using a Genetic Algorithm

    University essay from KTH/Optimeringslära och systemteori

    Author : Arian Abedin; Wolmir Ligai; [2018]
    Keywords : ;

    Abstract : In bridge design, a set of piles is referred to as a pile group. The design process of pile groups employed by many firms is currently manual, time consuming, and produces pile groups that are not robust against placement errors. READ MORE

  6. 5. Analysis of an Inclined Pile in Settling Soil

    University essay from KTH/Jord- och bergmekanik

    Author : Fredrik Resare; [2015]
    Keywords : Batter piles; raked piles; ground settlements; induced bending moments; lutande pålar; marksättning; nita elementmetoden; påle; transversalbelastning;

    Abstract : The use of inclined piles is an efficient way to handle horizontal forces in constructions. However, if the soil settles the structural bearing capacity of each pile is reduced because of induced bending moments in the pile. There are several reasons for a soil to settle, e.g. READ MORE
